To all whom it may concern.

Be it known that I, CLEMENS PASEL, a citizen of the German Empire, residing-at Heidhausen, near \Verden, Ruhr, Germany, have invented certain newand useful Improvements in Fuel-Injecting Devices, of which the following is a specification.

The atomizers generally used in fuel valves for internal combustion engines give, as a rule, a very high resistance for the passing of the fuel which is necessary to produce a good atomizing of the admitted quantity of fuel during greater load on the engine. With diminishing-load and the consequent smaller fuel consumption, this fuel passage resistance of the atomizer makes, however, a

considerable disturbance because the fuel chamber will be completely emptied of fuel;

and the freshly supplied, small quantity of fuel, will not be able to penetrate ,to the seat of the fuel needle and to displace the compressed injection air collected there, during the short available time. The consequence of this will be that the cold pressure air situated above the valve seat first enters the cylinder when the injection valve is opened, and will give occasion to mis-fire.

The object of-the invention isto provide an. atomizing device which is suitablefor all loads of the engine. This object is attained by providing a means through which the resistance which the atomizer offers to the working fuel to be introduced can be altered in accordance with the load on the engine. i

Three embodiments of the invention have been shown in the drawing wherein:

Figure 1 represents the parts of the fuel injecting device necessary to illustrate the invention with a plateaatqmizer in longitudinal section; Fig. 2 a cross section on llne 2-2 of Fig. 1. Fig. 3 a second embodiment omizer O consists of several atomizing plates 0 c 0 and 0 arranged one above another with aspace between. These plates are provided with holes 0 through which the fuel is driven on its way to the working cylinder.

"In distinction from other arrangements in known plate-atomizers wherein the holes of two adjacent plates are situated at different distances from thevalve axis, all of the holes c of the'several plates in this case are arranged at the same distance from the valve axis. The atomizing plates 0 and 0 are non-revolubly connected with the sleeve G surrounding the fuel needle D by means of keys 9 which sleeve can be turned by hand by means of a lever g or else by means of the governor of the engine (not shown). The intermediate plates 0 0* are on the other hand non-revolubly connected with the valve cage A by means of set screws H. As

a consequence of this arrangement the plates may be adjusted in such relative position by turning the sleeve G, that the holes of two adjacent plates may be displaced to greater or smaller degree relative to each other or be completely alined.

The operation of the described device is as follows: -With a great load of the engine,

the atomizing plates will be brought into the position illustrated in Figs. 1 and 2, wherein theholes c of adjacent plates are dislaced relative to each other as far as possi- 8,5

hle and the fuel consequently receives the greatest resistance in passing the atomizer.

Should the load of the'engine now fall and l the fuel transmission with it, the resistance will be diminished. in a simple manner by turning the sleeve G, for instance in the direction of the arrow m, Fig. 2. The plates 0 a will be turned with the sleeve G" to which they are non-revolubly connected,

While the plates 0 0 will retain their posi-' tion in the nozzle chamber; by this means the angle through which the holes a of two adjacent plates are displaced is gradually diminished, and these holes will finally come into alinement. The total resistance'of" the atomizer is thereby diminished so that even with a small load of the engine'and with small quantity of fuel, the fuel can still reach the valve seat.
